Palatal Volumetric Change Analysis Following Connective Tissue Graft With and Without Donor Site Augmentation

The goal of this randomized clinical trial is to compare whether soft tissue augmentation placed in the donor site following a gum graft harvesting leads to volumetric changes compared to non-augmented sites in the palate. The main questions it aims to answer are: * Are there tissue thickness changes between the two groups (control group and augmentation group)? * Are there volumetric changes in the donor site (palate) between the two groups in the short and long term? Participants will receive a gum graft and then based on what group they were randomly assigned, they will receive either a collagen matrix where the gum graft was taken (on the palate) or nothing will be placed. Researchers will compare non-augmented sites with augmented sites to see if there is a change in tissue thickness and volume.
